One of 321 aircraft dispatched to bomb the Hoechst synthetic oil factory at Sterkrade/Holten in the Ruhr valley, Captain Haldenby and crew took off from Croft at 22:54 hrs.

The attacking force consisted of two waves, one crossing the Dutch coast to the north of Rotterdam and the other to the south. It was here that four patrolling Heinkel 219’s of 1./NJG1 from Venlo made contact with the bombers bringing down ten aircraft on the outward leg of the raid.

The first of the ten casualties was the Halifax of Captain Haldenby and crew.

Engaged by Uffz. Hugo Oppermann, the bomber was hit with several bursts of canon fire and set ablaze at 00.53 hrs at a height of 20,000 feet near Brielle on Oostvoorne Island, LW433 finally crashing at Rucphen.

The two teen aged members of the crew, flight engineer Sgt. Peter Ager and gunner Sgt. Albert Boehmer, along with the wireless operator WO2 William Good, were all killed during the combat.

The other four crew members all managed to bale out as the stricken aircraft quickly lost height and plowed into the ground.

Haldenby, Downing and Dougherty were all captured and spent the rest of the war as PoW’s. Tom Inverarity of Lucky Lake, Saskatchewan, perhaps inherited some of the luck of the name of his home community and evaded capture spending the remainder of the war hidden by the resistance.

As for the success of the raid itself, upon reaching the target the attacking force found it to be covered by heavy cloud which obscured much of the Pathfinder markings. As a consequence, much of the bombing was scattered inflicting only minor damage to the production facilities.

In total, 31 aircraft were lost, with probably 21 shot down in mid air combat and ten by the flak defences.

(1) Flt Sgt Haldenby (J87396), Flt Sgt. Downing (J87791) and Sgt. Dougherty (J89923) were commissioned and promoted to Plt Off during their incarceration.

(2) Sgt. Inverarity successfully evaded until he was captured in Antwerpen on the 7th July 1944 .

Note regarding Halifax LW433.

This aircraft was first assigned to 424 Squadron based at Skipton on Swale, Yorkshire.

On the night of 19 February 1944, eight of the squadrons’ aircraft were detailed for operations to Leipzig. As the bombers were being taxied out to the runway, Halifax HX316 ran into the rear turret of LW433 the rotating propellors killing the rear gunner Plt Off Gerard Bottrell (J88402).

Plt Off Bottrell was estranged from his father Lawrence Bottrell, his birth mother, Elizabeth Chaweth, having died in 1935. Born in Detroit, Michigan, Gerard was raised in Parry Sound, Ontario by his Uncle Nelson and Aunt Annie.
